J Clin Periodontol 2011; 38: 499–508. doi: 10.1111/j.1600‐051X.2011.01708.x Aims: To investigate the incidence and reasons for tooth loss during active periodontal therapy (APT) and periodontal maintenance (PM) in a specialist institution. Material and methods: Retrospective data were collected from 273 patients (all compliers (AC)) and cross‐sectional data from 39 patients after discontinuation of PM (non‐compliers (NC)) for at least 7 years after APT. Descriptive statistics and regression analysis were performed. A comparison was made between AC and NC. The prognostic factors associated with tooth loss during PM were identified. Results: AC lost 1.3 teeth/patient during APT and 0.9 teeth/patient during PM (mean 10.7 years). Tooth loss due to periodontitis was 0.03 teeth/patient/year. The age of 60 was a significant predictor of tooth loss during PM (odds ratio of 2.1). NC lost 1.1 teeth/patient during APT and 2.7 teeth/patient during discontinuation (mean 9.6 years). Tooth loss due to periodontitis was 0.22 teeth/patient/year, a sevenfold increase (p<0.05) compared with AC. Regression analysis failed to identify any significant predictors for tooth loss during the discontinuation of PM. Conclusions: In this study, the provision of PM led to minimal tooth loss, especially due to periodontitis, for a mean period of 10 years after APT. The completion of APT without PM may predispose patients to lose more teeth compared with patients who undergo PM. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Clinical Periodontology Wiley
